Title: Improvements in and relating to two-stroke internal combustion engines
IPC: F02B33/38
Filed: 1960-12-20
Abstract: 915,230. Two-stroke engines. GENERAL MOTORS CORPORATION. Dec. 20, 1960 [Jan. 11, 1960], No. 43730/60. Classes 7(2) and 7(6) In a two-stroke V-engine each bank of cylinders has a separate cam-shaft 29 journalled in the upper part of each cylinder block and arranged so that the plane through the crankshaft and cam-shaft axes makes an equal angle with the vertical plane of symmetry of the engine and the plane through the axes of the cylinders of the respective bank. The cylinder block 4 is formed as a box girder with upper and lower portions 137, 118, containing cylinder liners 5, the space between the cylinder banks being closed in by webs 113, 120, to form an air receiver space to which air is delivered by a blower 15. The cam-shafts 29 are journalled in bores 46 in the block and actuate the four exhaust valves 25 in each cylinder head in pairs through push rods 50, rockers 34 and clevis members 35. The cam-shafts are driven through gear-wheels 60, Fig. 2, which incorporate balancing masses. The cylinder heads 17 are symmetrical so as to be usable for either the left-hand or right-hand bank and are formed with a flange 17<SP>1</SP> supporting the rocker cover 53. The cooling water pump 70, Fig. 5, driven from pulleys 58 on the cam-shafts, delivers to an oil cooler 94 bolted to the side of the crankcase, from which the water flows to the cooling jackets in the block, and head. A manifold 100 for conveying cooling water outside the cylinder head is provided in addition to the passages 168, 171 in the head. The oil cooler is mounted on a mounting plate 101 which also supports an oil filter 97, Fig. 5. The oil from the cooler passes to oil distribution manifolds 107<SP>1</SP>, 110 in the block. Oil drain recesses in the rocker compartment communicate with the cam-shaft galleries 46 which are connected to the crankcase to act as breathers. Cooling water galleries 54, 55, extend along both sides of the cylinder blocks and interconnect the cooling spaces around the cylinders. Inspection covers 128<SP>1</SP> are provided on the side of the blocks. The blower 15, Fig. 2, is driven from the cam-shaft gears 60 by an intermediate gear 84 and a fuel governor 85 is driven from the blower. The nozzles 129<SP>1</SP>, Fig. 11, through which the water enters the cylinder head cooling spaces direct the water against the exhaust passages 26.

Title: Improvements in or relating to Frequency Multipliers

Filed: 1968-10-01
Abstract: 1,181,190. Static frequency multipliers. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 1 Oct., 1968 [3 Oct., 1967], No. 46496/68. Heading H2F. . In order to reduce amplitude modulation of an oscillation of power supplied to a load V (Fig. 6) by a frequency multiplier, comprising a step recovery diode D fed from a generator G with a frequency # o  to be multiplied, via an impedance matching network TP and an energy storage inductor L, a plurality of quadripole delay lines (e.g. strip lines) are interposed between the diode and a resonance circuit F tuned to the desired output harmonic nf 0  of the input frequency # o  and excited by sufficiently narrow pulses from the diode which acts as a switch. The delay lines are of different lengths, so that line 12 provides one cycle (of the harmonic frequency) more delay than line 11, line 13 provides one cycle more delay than line 12 and so on. The number of lines equals the number of the harmonic desired. In the case shown, Fig. 6, the required harmonic is the 5th and the resonance circuit F which is tuned to the 5th harmonic, is excited five times during one cycle of the fundamental wave, and once during each cycle of the 5th harmonic, so that each oscillation in the 5th harmonic has the same amplitude. For large multiplication factors, e.g. twenty fold, the line delays may be so arranged that the resonance circuit F, which in this casewould be tuned to the 20th harmonic, is excited during every alternate self oscillation so that only ten instead of twenty lines would be required. For the 21st harmonic, seven lines may be provided and the tuned circuit would be excited at every third oscillation.

As described a door lock is of the semi-bolt type, opposed bolts 3, 4 thereof being actuated by a push rod working on a disc 12. The actuating mechanism is housed in a casing 6 with the panel rod projecting therefrom and the component is in the form of a plate 19 which is coupled to the forward face of the casing 6 by slides 25 and a lock 26 on the plate 19 and keyhole slots 24 and an aperture 27 in the casing respectively. A bar 30 on the inside of the forward wall of the casing engages the bolt 29 of the lock to prevent transverse movement between the casing 6 and plate 19. A slot 23 in the plate 19 co-operates with a groove provided in the push rod when the push-rod is in its extended bolt fastening condition. When detached from the casing 6 the plate is locked to a fitting adjacent the door (Fig. 1, not shown) to activate the lighting circuit of the building. Should there be a series of doors and fittings, the circuits of the fittings are connected in series.

Abstract: 1456541 Spectrophotometer GREENWOOD MILLS 11 Oct 1973 [24 April 1973] 47488/73 Heading G1A A spectrophotometer utilizes a small digital computer Fig. 7 (not shown) to process the outputs of 16 photodiodes 124, each having a filter 126 of different spectral sensitivity and being arranged to view a transparent port 24 in a substantially spherical enclosure 20, 22 having a reflective inner surface. Each time before the sample is measured (by placing over the port 24) the spectrophotometer is calibrated automatically by the digital computer by positioning a vitrolite plate 89 then a black colour standard 66 over the transparent port 24 by means of a depressable plunger mechanism 50. The vitrolite colour standard is on the end of a plunger 88 which when depressed activates a switch 106 which starts a computer programme automatically in the computer and that then allows a certain time for the black standard 66 to be swung in position by lever 68 and so that it can be placed over the port, and, time for the sample to be positioned. The interior of the enclosure 20, 22 is illuminated through a port 26 by a source 32 that is cooled by a blower Fig. 6 (not shown) directing hot air via ducts away from the lamp. The whole arrangement has a system of cooling fans e.g. 52, 54 but also Figs. 3, 4, 5 (not shown) to stabilize the temperature of the system. The description discloses a typical computer programme for handling the signals from photo diodes that have been amplified, multi-plexed and passed through an A/D converter.
